Q. When amount of ADH decreases in blood, micturition: 
(a) Increases 
(b) Decreases 
(c) Remains unaffected 
(d) None of these 

Q. Hormones produced by anterior lobe of pituitary: 
(a) control calcium level in blood 
(b) stimulate thyroid and other endocrine glands  
(c) initiate alarm reaction 
(d) regulate water balance in body

Dear student.

1. The correct answer is  (a) Increases.

ADH is secreted by pituitary gland in order to control the volume and concentration of the urine released in a person's body in various situations. Due to decrease in the amount of ADH,  excretion of abnormally large volumes of dilute urine will take place.  Micturition is the process by which the urine from the urinary bladder is excreted.

2. The correct answer is (b) stimulate thyroid and other endocrine glands.

Anterior pituitary secretes Growth hormone, Thyroid stimulating hormone, Adrenocorticotropic hormone, Prolactin hormone, Gonadotrophic hormone (Follicle stimulating hormone, Luteinizing hormone).

Growth hormone stimulates growth.
Thyroid stimulating hormone controls growth and activity of thyroid gland.
Adrenocorticotropic hormone stimulates cortex of adrenal gland to produce hormones.
Prolactin hormone stimulates corpus luteum of ovary to secrete progesterone.
Follicle stimulating hormone stimulates growth of ovarian follicles and secretion of estrogens in female and spermatogenesis in male.
Luteinizing hormone stimulates corpus luteum of ovary to secrete progesterone and in males activates Leydig's cells of testis to secrete androgens.

Regards.
